Causes and solutions of speed ratio reduction of marine hydraulic pump

The internal piston pump and cylinder cooperation of the engine high pressure fuel pump manufacturer is not good or the clearance of the distributor is improper; the main shaft bearing, rolling bearing and other parts are destroyed; the problem of hydraulic pump is the problem or imbalance of hydraulic auxiliary parts.

Cleaning method

Repair and replace motor and clean hydraulic oil strictly; replace parts for maintenance, hydraulic pump maintenance or adjust hydraulic auxiliary parts.

The second of marine hydraulic maintenance: the reason of output rotation reduction

The cooperation between the piston pump and the cylinder in the motor is not good or the clearance of the distributor is improper; the main shaft bearing, rolling bearing and other parts are damaged; the hydraulic pump problem, the hydraulic auxiliary parts problem or the imbalance.

Cleaning method

Repair and replace motor and clean hydraulic oil strictly; replace parts for maintenance, hydraulic pump maintenance or adjust hydraulic auxiliary parts.

The third of marine hydraulic maintenance: the reason for reducing the reliability of low speed gear

The environmental pollution of hydraulic oil causes damage to parts in the motor; the abnormal hydraulic pump makes the oil provided appear abnormal; the gas is infiltrated into the hydraulic management system, which makes the working pressure show wobbling or the hydraulic oil has cavitation.

Cleaning method

Repair and replace the motor, clean up the hydraulic oil strictly, inquire the relevant components and accessories, recover and treat all oil standards provided normally; clean the price of the high-pressure fuel pump of the steam body engine of the management system.

The fourth of marine hydraulic maintenance: the reason for noise expansion

The total flow of working pressure of the management system is changed beyond the rated current, and the internal parts of the motor are damaged; the rolling bearing, motor stator, spindle bearing and other damage; the hydraulic oil environmental pollution makes the sliding friction force of the fitness components expand; the fitness components show looseness and bias; the hydraulic impact and hydraulic oil hole of the management system.

Cleaning method

Search for the reasons for the expansion of working pressure, repair and replace the motor, clean up hydraulic oil, correct cooperation or replace components, and clean up the steam body of management system.

The fifth of marine hydraulic maintenance: leakage plus reasons

The screw screw is loose due to the vibration of mechanical equipment; the hydraulic seal is damaged; the environment pollution of hydraulic oil damages the parts.

Cleaning method

Tighten screw, replace hydraulic seal, replace maintenance components, clean hydraulic oil.
